CSTI is one of those Swiss companies that move quietly, yet whose presence steadily shapes the digital landscape of SMEs. Based in Geneva since 2009, the company founded by Rémy Duchet and Yves Oberhansli has grown against the grain of a market undergoing rapid consolidation, where international giants absorb smaller players and impose their standards. In this shifting environment, CSTI has chosen a different path: proximity, independence and deep expertise rooted in the realities of local businesses.

Digital sovereignty in the service of Swiss SMEs

From the outset, the company positioned itself as a comprehensive technology partner, capable of handling hosting, infrastructure, IT fleet management, consulting and hardware sales. Beyond this broad service offering, however, lies a philosophy: one of customisation, attentive listening and transparency. “We built CSTI on a simple idea: truly understand where our clients want to go, and help them get there with tailored solutions, not standardised models,” explains Rémy Duchet. That approach, which may seem straightforward, becomes a genuine competitive advantage in a market where large groups often prioritise standardisation and scale.

CSTI’s positioning rests on a dual strength: rare engineering expertise in critical infrastructure, and the operation of its own datacenters, which enables it to run a 100% Swiss cloud — secure, stable and fully controlled.

Such mastery of the IT chain is more than a technical advantage; it is the foundation of the reliability promise the company offers its clients. “When you manage your own datacenters, you do not have the right to make mistakes. Every decision shapes the future. We apply that same level of rigour to our own infrastructure as we do to all our clients’ systems,” notes Yves Oberhansli. In a market saturated with standardised solutions, CSTI stands out through a singular ability to guarantee a sovereign environment built to last.

Yet the company’s distinctiveness lies not only in its technology. It lies equally in the way it stands alongside businesses. Where large cloud providers stop at delivering a hosted service, CSTI goes all the way to the end user. “If an employee has a problem with their application, we are there. Not a chatbot, not an anonymous platform: a person. That human connection makes all the difference,” says Rémy Duchet. This almost artisanal closeness — the willingness to step in physically, to speak the customer’s language even when it is not technical — has become a defining feature of the CSTI identity. The company now serves an exceptionally broad client base, from microbusinesses with three users to major international groups. That diversity does not concern the founders; on the contrary, it drives them. “Every company has its own specifics, but they all share one need: to be understood,” says Yves Oberhansli.

“CSTI sees itself as a trusted architect in a digital world that is constantly accelerating: a partner able to deliver reliability, stability and sovereignty”

CSTI: a long-term vision

CSTI’s areas of expertise form a coherent ecosystem designed to give companies uninterrupted technological continuity: hosting (cloud, dedicated servers, websites, CSTI Drive, Mailbox), managed services (full or partial IT fleet management), consulting (strategy, architecture, projects) and hardware sales. Four complementary pillars that interlock to create a complete value chain, controlled from end to end.

“We do not sell technical building blocks, we build environments that work, last and adapt”

That integration is not a marketing argument; it reflects a way of working. “We do not sell technical building blocks, we build environments that work, last and adapt,” says Rémy Duchet. Customisation is not a promise but a daily discipline: analysing, adjusting and calibrating each solution so that it matches the client’s actual needs precisely. “With us, the client only pays for what they use. Nothing more,” he adds. In a sector where layering services is often the norm, the company champions a more restrained, fairer model, firmly focused on practical value.

CSTI sees itself as a trusted architect in a digital world that is constantly accelerating: a partner able to deliver reliability, stability and sovereignty, on whom companies can truly rely. Its ambition is not simply to meet today’s needs, but to build infrastructures that prepare businesses for the challenges of tomorrow.
